KingMix 355PC®
High performance concrete admixture based on polycarboxylic polymers.
SpecWorld has the Spec Pack, CSI specification and drawings for registered specifiers.
Overview
KingMix 355PC is a high performance super plasticising admixture based on polycarboxylic polymers with long chains specially designed to enable the water content of the concrete to perform more effectively.
This effect can be used in high strength concrete and flowable concrete mixes, to achieve highest concrete durability and performance.
Where to use
- To produce high quality concrete of improved durability and water tightness.
- High strength and high performance concrete.
- Improved cohesion allow for use in mass concrete pours and piling.
Why use it
- Optimizes cement utilization.
- Improves shrinkage and creep behaviors.
- High density and impermeable concrete through very high water reduction.
- Higher early and ultimate compressive strengths.
- Minimizes segregation and bleeding problems by improving cohesion.
- Increases durability and resistance to aggressive atmospheric conditions thorough reduced permeability.
COMPATIBILITY
KingMix 355PC can be used with all types of Portland cement and cement replacement materials. KingMix 355PC should not be used in conjunction with other admixtures unless KINGKRETE Technical Department approval is obtained.
Technical properties
Values @ 25°C
| Colour | Yellowish to brownish liquid |
|---|---|
| Freezing point | ≈ -3°C |
| Specific gravity | 1.06 ± 0.02 |
| Chloride content | Nil |
| Air entrainment | Typically less than 2% additional air is entrained above control mix at normal dosages |
DOSAGE
The guidance dosage of KingMix 355PC is 0.5 - 2.5 litre per 100 kg of cementitious materials in the mix, including GGBFS, PFA or micro-silica.
Representative trials should be conducted to determine the optimum dosage of KingMix 355PC to meet the performance requirements by using the materials and conditions in actual use.
EFFECTS OF OVER DOSAGE
Over dosing of KingMix 355PC will cause the following:
- Significant increase in retardation.
- Increase in workability.
Ultimate concrete strength will not be adversely affected and will generally be increased provided that proper concrete curing is maintained.
Standards and approvals
KingMix 355PC complies with ASTM C494, Type G.
How to use
Method of use
KingMix 355PC should be added to the concrete with the mixing water to achieve optimum performance.
An automatic dispenser should be used to dispense the correct quantity of KingMix 355PC to the concrete mix.
Cleaning
KingMix 355PC can be washed with fresh cold water.
Coverage, packaging and storage
Packaging
KingMix 355PC is available in 25 litre pails, 210 litre drums and 1000 litre bulks supply.
Storage
Shelf life is 1 year when stored under cover, out of direct sunlight and protected from extremes of temperature.
Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult KingKrete's Technical Services Department.
Health and safety
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs. Treat splashes to eyes and skin immediately. If accidentally ingested, seek medical attention. Reseal containers after use. Use in well ventilated areas and avoid inhalation.
